Description
This paper presents the physical design of the Main Linac (ML) for the STCF, accelerating 1~GeV electron and positron beams to 1--3.5~GeV for both off-axis (1~nC) and swap-out (8.5~nC) injection. An interleaved scheme divides 36 accelerating structures into two groups, independently controlling energy gain and longitudinal phase space for each species. At the nominal 2~GeV output, simulations with elegant demonstrate well-controlled energy spread and emittance. After Beam Based Alignment correction, orbit oscillation is constrained below 1~mm, with exit geometric emittances of 0.28~nm (off-axis) and 3.30~nm (swap-out), both meeting injection requirements.
